Title: Electronic cross point switch device
Inventor: MATSUDA YOSHIO
IPC: H04L12/931
Filed: 1992-01-18
Abstract: PURPOSE:To obtain a higher signal transmission speed by providing a means driving differentially output data line pairs in response to a differential potential of input data line pairs on each switching cell. CONSTITUTION:A unit switch cell SCa turns on NMOS transistors(TRs) 61, 63 when a slave latch circuit 110 holds a high level switch control signal CNT. Thus, when the signal on an input data line 1a is at a high level, a low level signal is given to art output data line 2a. On the other hand, since a signal on an input data line 1b is at a low level, a potential on the output data line 2b is at a high level by the operation of a current mirror circuit in a load circuit 31. Thus, a switching cell SCa output differential output data signals ODa,ODb with respect to differential input data signals IDa,IDb to obtain a high signal transmission speed and the occupied area on a semiconductor substrate is reduced.

Title: Radiant space heater
Inventor: TAGI AKIO
IPC: F24C15/20
Filed: 1989-01-13
Abstract: PURPOSE:To improve the heating efficiency by providing a radiator which, being heated by the hot air from a heating source, radiates heat forwardly, and a topped hood which collects the hot air from the heating source and guide the same to the radiator. CONSTITUTION:Part of the burning heat generated in the burning tube 14 is released directly forwardly as radiant heat, but most of the remaining part is released upwardly as convection heat. As the radiant heat is recovered by a hood 20 and is guided to a radiator 17, the temperature of the radiator 17 itself is increased enough to generate radiant heat forwardly. The heat which would otherwise be lost above the top plate 16 can thus be effectively recycled as the forward radiant heat. Such effect is heightened by the presence of hood 20, and, because the top plate 15 can be held at a relatively low temperature, it does not require the expensive enamel finishing but the application of heat resistant paint will be enough. Further, since the radiator 17 is coated with far infrared ray radiating paint 19, it radiates far infrared rays, enhancing the effective radiant space heating.

Title: Production of optical fiber coupler
Inventor: SUGANUMA HIROSHI
IPC: G02B6/28
Filed: 1990-01-17
Abstract: PURPOSE:To eliminate the spacing between optical fibers by reducing the outside diameter of the clad of at least one piece or above among plural pieces of optical fibers by using an aq. fluoronitric acid soln. and thereby varying the clad diameter in a tapered part with good accuracy. CONSTITUTION:The coating is removed in the longitudinal direction of the optical fibers to expose the glass part prior to etching and this part is etched to reduce the diameter. The parts of the optical fibers where the coverings are removed are immersed in the aq. fluoronitric acid soln. and are thereby etched; therefore, the diameter of only the etched part is reduced and both ends are the same diameter as the diameter of ordinary optical fibers. The connectability of the coupler and the fibers is thus good. The reduction of the outside diameter by the etching is uniformized over the entire length and the etched part is formed to the uniform diameter and, therefore, a spacing is not generated when the fibers are brought into tight contact with each other. The integration by welding is thus possible. Since the finished diameter is controllable by the etching time, the controllability is good and always constant characteristics of the coupler are obtd.

Title: Preventive and remedy for photohypersensitivity
Inventor: KIMURA SHIYUUICHI
IPC: A61P3/00
Filed: 1979-01-25
Abstract: PURPOSE: A preventive and remedy for photohypersensitivity caused by pheophorbid that contains pantethine to prevent hemolysis at a high rate.  
     CONSTITUTION: Said preventive and remedy contains pantethine that is widely used as a medicine, especially lipid metabolism improver. Chlorella disease that has occurred in Tokyo recently is one of photohypersensitivity, which is caused by pheophorbid (the substance is formed by removing magnesium atom from chlorophyll) remaining in body when a large amount of chlorella is taken, which forms free radicals when light is irradiated to cause inflammation and necrosis. Pantethine prevents necrosis at a high rate in spite of existence of pheophorbid, thus functioning as a preventive and remedy for photohypersensitivity.

IPC: C02F3/08
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To obtain a carrier for microorganisms which can maintain microorganisms in a high density and shows excellent nitrification and denitrification without causing wear or tangling even when it is used for a long time, by constituting the carrier for microorganisms of aggregated ultrafine fibers and a resin which is partially present in continuous pores of the aggregate. SOLUTION: The carrier for microorganisms is preferably used for water treatment to biologically decompose and remove substances dissolved in the water and the carrier consists of aggregated ultrafine fibers and a resin partially present in continuous pores of the aggregate. In this method, a fiber which can form ultrafine fibers is used to obtain the ultrafine fibers and/or bundles of these. The single fiber of the ultrafine fibers is preferably controlled to have 0.001 to 1 denier. As for the resin, a urethane polymer, polyvinylalcohol gel, or a diester polymer gel of polyethylene glycol and acrylic acid or methacrylic acid can be used. The fiber which forms ultrafine fibers is produced, for example, by bundling ultrafine fibers just after spinning and partially and lightly adhering the fibers into one fiber.

Title: Heat retaining cover of additional burning type bathtub
Inventor: FUJINUMA TOSHIO
IPC: F24H1/00
Filed: 1984-01-19
Abstract: PURPOSE:To enable to prevent the trouble due to the overheating of a bath heater from occurring by a structure wherein a suction cup made of material with elastomeric property is attached onto the inner wall surface of a bathtub and a conducting mechanism formed by shape memory alloy is provided at the upper part of the cup. CONSTITUTION:A cover 5 separates a bathtub 1 from a bath heater 2 by covering a hot water inlet 3 and a hot water outlet 4. In addition, the cover 5 is made of material such as synthetic rubber or the like and serves as a kind of suction cups by being given elasticity to itself. A conducting piece 6 is arranged in the interior of the cover 5 and made of shape memory alloy so as to response to the water, which has a temperature exceeding the certain fixed value and enters the interior of the cover 5. When the bath heater 2 is heated, the hot water having a temperature of about 50-60 deg.C enters the interior of the cover 5, resulting in heating the conducting piece 6. The heating of the conducting piece 6 causes a part of it to protrude against the inner wall surface of the bathtub, resulting in separating the cover 5 from said inner wall. As a result, the inside and outside of the cover 5 conduct to each other and the adsorbability of the cover 5 is lost and finally the cover 5 is removed from the inner wall. Accordingly, when the bath heater is fired, the cover is automatically removed by itself, resulting in solving the overheating accident of the bath heater.

Title: Power source switching system
Inventor: TAKADA SHINJI
IPC: H02P25/20
Filed: 1985-01-18
Abstract: PURPOSE:To prevent a thermal damage of a motor by stopping switching by detecting by a temperature detector until the quantity of heat stored in the motor is returned to sufficiently normal state when a variable frequency power source is switched to a commercial power source. CONSTITUTION:A large torque might be generated by the rotating speed operated by a variable frequency power source 2 before switching to a commercial power source 1. Thus, a current flowed at switching time is increased, and heat is stored in a motor 6 at switching time. Thus, when the power source 2 is switched to the source 1, the switchings of switches 3, 4, 5 are locked if a temperature detector which operates when the temperature of the motor is the prescribed value or higher is operated, thereby preventing the motor from abnormally overheating.
